As an IT guy, start a ticket.
Those update messages are likely from an automated system, and the updates are probably controlled by a completely independent system that nobody looks at regularly.
By submitting exactly what you did here as a ticket to the IT team, you're pushing them to check in on those systems and approve updates that haven't been approved.
Yes, it's dumb. The updates should be automatically approved. Obviously they're not, or something has prevented them from approving it.
Personally, as IT, if I get a ticket about this, I'd want to dig into why the update wasn't approved and make sure future updates get approved without delay; solving both the immediate issue and all related issues in the future. However, if I'm not aware of the issue, I can't really fix it. From their view, they likely only see a dashboard of all devices and yours (along with others) are probably flagged as needing an update. This is extremely common and probably entirely ignored under normal circumstances. Almost every one of the systems I administrate at work have updates that are pending. Either the system hasn't been restarted (mainly desktops and servers and such) or, if it's reliant on a user taking action, I assume the user doesn't care enough about the update to bother running it.... The idea that the update hasn't been approved or that there's a problem getting or applying the update, doesn't even enter my brain as a possibility until someone complains. Simply put, I don't have time to investigate every pending update that has not yet been applied. You'd almost need a dedicated person just to keep an eye on updates in order to keep on top of them, and nobody pays an IT person solely to look after updates.
So I'm busy fixing Debbie's printer, and Joe's scanner, and Frank's email that's slowing the date in that strange format again because he somehow changed his regional settings to the UK again....
Do your IT team a favour and send them this. I promise you that they'll be grateful, even if they don't seem like it. Bluntly, this is a perfect amount of information.
I get requests that range from "please call me when you have a chance" to "this specific function in this specific program is doing a thing that's different from what I see on a coworker's screen and I like how their screen shows it better because it reminds me of my grandchild's grade 3 school play where they played a tree." Ok Linda, thanks, I really didn't need to know about little Timmy's school play.... Users either give us nothing, or way too much irrelevant data. So this image shows exactly what is required for a diagnosis. Either the messages will be stopped or the update will be approved.
